how to increase the power supply
i have 100 amp service which is about thirty years old and seems fine until i use more than one appliance a circut, a carpet cleaner and television on at the same time blows the circuit. microwave and coffee maker likewise. 10,000btu air conditioner operating at full tilt blows a circuit while another of the same in a different outlet doesn't.
what would be the best way to bring the power up and increase room for more breakers[i have only one slot left]. another panel or should i increase the power in to the house? i haven't contacted an electrician yet but would not do anything without one. i just don't want to sound that stupid. i don't want to be oversold.
